Indian holy man just entertaining king (5)
I believe the answer is:
fakir
'indian holy man' is the definition.
'fakir' can be an answer for 'man' (I have seen 'Holy man ' mean 'fakir' so perhaps 'man' could also mean 'fakir'). I am not sure about the 'indian holy' bit.
'just entertaining king' is the wordplay.
'just' becomes 'fair' (just can mean fair in the sense of showing justice).
'entertaining' means one lot of letters goes inside another (inviting in, as for dinner).
'king' becomes 'K' (abbreviation for king in chess).
'fair' placed around 'k' is 'FAKIR'.
Can you help me to learn more?
(Other definitions for fakir that I've seen before include "Indian religious ascetic" , "Ascetic type" , "Religious mendicant in India" , "Eastern holy man" , "Muslim ascetic - Hindu holy man" .)
